With an extremly effecient design and perfectly tuned software the ESS S54 Z4M VT Series supercharger system delivers supercar performance along with the quality and reliability ESS customers have come to expect. This kit is designed as a 100% bolt on package with no irreversiblecustom fabrication to the vehicle.

*The Z4M is very sensitive to vehicle sensor feedback. It is critical that all sensors and factory hardware components are in proper working condition. It is not uncommon to have the vehicle go into a power reduction mode during operation due to a fault during vehicle self diagnostics. For racing applications we recommend a stand alone engine management system to ensure 100% power at all times.
